From planets and supermassive black holes to cells and DNA, to the human voice, everything vibrates and creates sound. The Cassini–Huygens spacecraft was the first to record Saturn's sounds, which relate to tiny radio sources moving up and down along Saturn's magnetic field lines.[21] The sound of a black hole in the heart of the Perseus galaxy cluster, 300 million light-years from Earth was recorded as 57 octaves below middle C in the note of B flat. Each black hole has been found to have a specific unique sound, the consequence of vibrating gasses.[22] Jim Gimzewski, a nanotechnologist at the University of California, Los Angeles (UCLA) and Andrew Pelling have discovered the sound of yeast cells are clearly distinguishable from mammalian cells.[23] Using atomic force microscopy (AFM) to detect cell wall movement, and converting the oscillations to sound frequencies, the researchers found that although these frequencies are within the human hearing range, the amplitude is not sufficient to be heard by the human ear.[24] Amplifying the oscillating signals and then converting the sounds into audio format, the original frequencies are maintained and they were able to listen directly to the cell’s sound.[25] Earlier research conducted in 1988 by Susan Alexjander and biomolecular engineer Dr. David Deamer measured the vibrational frequencies of the four DNA base molecules, translating each into a unique sound.[26] On a human scale, people can be identified on the phone solely by the sound of their voice.[27]
Edwards theory of human bioacoustic therapy originates from the observation that brain-wave frequencies are electrical impulses that fluctuate rhythmically in distinct patterns, clearly seen and measured by an electroencephalogram, commonly abbreviated EEG.[28] As the brain perceives sound and delivers these frequency patterns to the body via nerve pathways, the sound wave pulses serve as directives along the electromagnetic field lines of the body, functioning to sustain structural integrity and emotional equilibrium.[11] The laryngeal nerve, a branch of the vagus nerve, innervates larynx muscles which create vocal sounds by oscillating the vocal cords. This direct conduit from the brain and body to the vocal cords suggests a message pathway, supporting the theory that frequencies in the voice are representations of activity in the autonomic nervous system. Furthermore, the vocal cords are entrained to reflect the frequency communication between the body and brain via their involvement in this pathway. Bioacoustic therapy vocal profiling technique is used to detect this frequency communication. By recording vocal frequencies in Fast Fourier Transform (FFT), information is collected and analyzed to delineate patterns of coherence and dissonance. Bioacoustics therapy researches these patterns for specific clues regarding the health of the speaker, and the relationship between discordant patterns and symptoms of disease and distress. When discordance is identified, low frequency analog sound formulas are delivered as a means of balancing the disharmony, promoting the body’s innate ability to self-heal through entrainment. Additionally, the frequency patterns are studied for their relationship to a predictable mathematical matrix used to formulate sound frequency interventions. Case studies also suggest that the specific beat created by low frequency sound formulas is an integral component of targeting specific structures.[29]
